ATTOR N EY Sept. 13, 1966 W. FREEDMANN ROTARY BRUSH FOR SKIN AND BODYTREATMENT Filed Aug. 15, 1963 I5 Sheets-Sheet 5 //V/ [/V'r0/P WALTER FR!EDMANN BY 9% ATTORNEY 1 Claim. ((51. 128--56) This invention relates toa device for skin and body treatment by which the treating agent is fedto the skin or body by means of a rotating brush.

It is known to apply ointments, creams or lotions to parts of the bodyby brushing the agent in or massaging it in by hand. Massage tools havefor instance become known which are provided with nozzles and can beattached to a tube containing a treating agent. Brushes have also beenformed that were attached to containers for hair lotions, massage oiletc. and released the treating agent through bores, hollow bristles ornozzles in the brush when passing over the skin. Since the right way ofrelease of the treating agents requires considerable skill on the partof the operator the efficacy of these devices is rather uneven. Thistype of application is furthermore strenuous and because of thenecessary pressure of application frequently is just as little suited toa sensitive skin as the direct rubbing in by hand without any tool.While power driven rotating brushes for massage are likewise known,application of a liquid or pasty treating agent in these devices had tobe carried out separately.

It is therefore an object of the present invention to provide a deviceintroducing a treating agent to the skin with a higher degree ofuniformity, intensity and to a greater depth as has been possible withpresently known hand brushes and massaging devices.

The invention generally relates to a device for skin and body treatmenthaving a rotary brush driven through a flexible shaft and provided witha central feed duct terminating tlush with the face of the body of thebrush to feed treatment liquid from a reservoir.

in the accompanying drawings:

FIG. 1 is a side view of a tripod showing an overall view of anembodiment of the invention;

FIG. 2 is a side view, partially in section, showing only the drivemechanism and feed ducts of an embodiment of the rotary brush of theinvention;

FIG. 3 is a side view at a 90 angle relative to the view of FIG. 2showing the brush and drive parts;

FIG. 4 is another embodiment, in side View, of the brush of theinvention and of its feed and drive parts.

The device of BIG. 1, which is intended mainly for institutional use,has a tripod 1 carrying an electric motor 2. The connection to a powersource is effected through a cable 3 while the flexible shaft 5 providesthe mechanical dnive for a reduction gear disposed in a hand piece 4which in turn carries the exchangeable brush 6. A tubing 8 attached tothe hand piece serves to feed the treating agent from the container ordrip bottle 7 to the rotary brush to be present the-re at the point oftreat-ment during the operation of the brush. The treatment agent maycomprise cold or hot water or a special treating solution or lotion.

The other figures show certain parts of various embodiments of thedevice on an enlarged scale and in a more or less schematic manner. Thedevice of FIGS. 2 and 3 has a flexible shaft 15 which enters the handle14 and operates a reduction gear housed in the brush nitcd States Patent0 3,272,200 Patented Sept. 13, 1966 casing consisting essentially of arack or worm gear or other operative part formed on the drive shaftwhich matches with a pinion or bevel gear to drive the exchangeablebrush 16, having bristles 17 in a manner known per se and therefore notfurther illustrated here.

The shaft for brush 16 is formed by a hollow tube 19. The treating agentis passed to the interior of the hollow shaft 19 through the tubing 18attached to the shaft 19 by means of a rigid attachment piece. The shaft19 extends through the rigid brush body 46 to its front face 47. Aconventional slip clutch (not shown) may be provided between thereduction gear 10 and the rotary brush 16 to disconnect the drivemechanism whenever too much pressure is exerted while the brush bearsagainst the body of the patient.

FIG. 4 shows an embodiment, likewise in diagrammatical form, which issimilar to that of FIG. 3 but has a different front piece 24. Theflexible drive shaft 25 in this case leads to a reduction gear 20 inform of a bevel gear which drives the rotary brush 26. A slip clutch mayagain be interposed. The supply of the treating medium takes placethrough the hollow shaft 29 and connecting tubing 28.

A continuous control and adjustment of the tempera ture andconcentration of the treating liquid is possible. The supply lines canbe controlled by valves. The shape of the handle as well as the form andsize of the rotary brush may be adapted to the requirements of thevarious treatments. The speed of rotation of the motor may likewise besubject to adjustment by the operator.

Devices of the type described can be used also for the treatment of thescalp for instance to combat and prevent loss of hair in which case forinstance a shampoo and a treating lotion may be supplied together 'whilesubjecting the scalp to the brush massage.

A further application is the treatment of the face in which case, forinstance, packs may be applied which afterwards can then be taken off bymeans of the rotary brush and simultaneous passing of warm water to theskin. Subsequently and as desired, a nourishing or regenerative creammay be applied which is rubbed into the skin by the rotary brush.Finally an astringent lotion may be applied by connecting the supplylines to a vessel containing the latter.

As will be understood not only the treating medium but the size andshape of the rotating brushes and the thickness and length of thebristles 17 may be varied within a wide scope.

Regarding the size of the brush, disk brushes for use in facialtreatment may have a disk diameter from about one half to a little overone inch. A larger size disk brush of close to five inches may be usedfor the treatment of other body parts.

The brushes should have a suitable handle to permit the opera-tor toapply the brush to the skin for the required period of treatment. Asexplained, the axle of the brush is hollow and can be used as the feedline, for instance, of a treating lotion or of air under pressure or ofcarbon dioxide, all of which will penetrate into the pores of the skinonce the pores have been opened up by the brush.

Treatment of the scalp, facial treatment and body treatment can beeffected both in so-called dry methods, that is, in air withsimultaneous introduction of treating agents or as part of ahydrotherapy where the treatment involves immersion of the body part inWater and simultaneous feeding of the treating agent.

Various modifications are possible within the scope of the inventiveconcept.

What I claim and desire to secure by Letters Patent is:

Apparatus for skin and body treatment comprising a stationary motor; ahandle portion separate from said motor; treatment brush means having arigid disc shape body with bristles extending therefrom; a hollow tubereceived in and secured to said body ro-tatably mounted in said handleportion, said tube extending through said body and having one endterminating flush with the face thereof on the side adjoining thebristles and located centrally of the axes of rotation thereof; meansincluding a flexible shaft interconnecting the hollow tube and saidmotor to transmit rotation to said tube and thus to said body; a fluidreservoir; and means interconnecting said fluid reservoir and the otherend of said hollow tube to deliver fluid thereto.
